BULK-HEAD CONSTRUCTION FOR REFRIGERATOR CARS Application led December 27, 1529. Serial No. 416,856.

My present invention pertains to bulk-head construction for refrigerato-r cars, and it contemplates the provision of a construction designed for use in banana transporting refrigerator cars, particularly but not necessarily and one that embodies relatively arranged elements through the.. medium of .which the cargo in the car may be bulk-headed at any point intermediate the ice compartment and the door of the car whereby chilling and consequent deterioration of the cargo is precluded. y

The invention further contemplates the provision of bulk-heading means that are adapted to be swung out of the way and retained in such position when occasiondemands.

Other advantageousfeatures of the inven` tion may be fully understood from the fol- `lowingdescription and claims when the same are read in connection with the drawings ae-` companying and forming part of this speciic'ation, in which Figure 1 is a longitudinal sectional view` of a car showing my novel bulk-head construction arranged therein and in normal position.

Figure 2 is a similar view showing the bulkhead construction thrown out of the way and positioned in the roof of the car.

Figure 3 is a transverse sectional View taken in the plane indicated by the line 3 3 of Figure 1, looking in the direction of the arrows andshowing the gates down.

' Figure 4' is a view partly in section and partly in top plan showing the device as it appears when looking in the direction indicated by the-arrows in thel plane 4-4 of Figure 3.

Figure 5. is a horizontal detail sectional View of my novel slide bolt arrangement for assisting in securing the gate with resp-ect to the side bars.

Figure 6 is a detail horizontal sectional View of the track and trolley used in my device.

Similar numerals ofv reference designate corresponding parts in all the views of the drawings. l.

the car is a track 4 which in reality is a series 55 of channel-shaped rails that are adapted to be engaged by the trolleys 5. `These trolleys are fast on shafts 6 and secured in pivotal manner on the shafts 6 are depending members 7. These members in turn pivotally engage bars 8 that also engage on their lower ends rails 9 that form a portion of rthe bulkheading gates. In order to limit the movement of the trolleys with respect to the rails I provide a stop of `Ushaped construction 05 indicated by 10.

Preferably the center rails of the gates are provided with members 11 in which props 12 are pivoted and manifestly pressure against the gates will merely tend to force 7 the pointed ends of these props into the floor 13 of the car thereby precluding movement ofthe gates toward each other with respect to the door opening.V

Arranged against the inner wall of the car are rack-bars 14 while pivotally secured to the door frame 2 are rack-bars 15 and 16. These bars '15 and 16 are pivoted at 17 and 18 and when down are normally held in the door opening against casual displacement by k per end of one door post 2 is a keeper 21 that S5 holds the bar 15 in vertical positionwhile on the other post is a keeper 22 that holds the bar 16 in vertical position.

The end posts 23 of thegate have each a slot therein in which a slide bolt 24 actuable by the handle H is adapted to be moved into and out of the slots 14 of the nearest rack thereto. A door cross beam 26 is arranged near the ceiling and is provided with 'openings 95 27 for a purpose hereinafter noted. An opening 28 is also provided in the frame 2 near its-upper end. Manifestly each gate is provided with two sets of slide bolts'the pur' pose for which will be apparent.

cargo may be completed In-tlie practical operation of the invention, it is first determined the amount of space to be used by the cargo or the placing of the and the bars 8 which engage the rails of the gate are pushed along the tracks to the desired point and then by merely pushing the handle II of the slide bolts 24 to yforce the bolts into the openings 14 of the rack bar 14 and dropping the props 12 to aposition such as that show n in Figure 1 the gates or bulk-heading element will be rigidly held in position against pressure of the cargo. If it is desired to employ 'a portion of the door way the bulk-head may be so positioned in the door way by throwing the pivoted racks 15 and 16 into the position shown in Figure land then forcing the slide bolts into the apertures 14 of said `pivoted rack. Manifestly the cargo carrying capacity of the car is increased as heretofore space in the door-way could not be utilized because the bulk-head gates could not be positioned in said door-Way. i

When it is desired to put the bulk-head construction out of the way it is merely necessary to release the slide bolts from their rack bar engagement and gates will retaln 1n Vae throw the racks into the position shown in Figure 2. The bars 8 which are pivoted on the hangers 7 will Jermit pushing of the bulk-head gates upwar ly and when said gates are in a parallel position with respect to the ceiling 3 of the car the slide bolts may be forced into the openings 27 of the door cross beam 26 and the opening 28 of the frame beam 2. This construction the the position show-n in VFigure 2.

It will be manifest from the foregoing that the matter of bulk heading a refrigerator car may be accomplished with but a slight amount of effort and the apparent'saving in bulk-head space is a matter ofy great saving in the shipment of perishable cargo,

What I claim is depending arms pivotally mounted with respect to the trolleys, bulk-head gates secured to the depending members and means formed on the gates and adapted to engage the notches of the bars vand further ada ted to engage the slots of the door beam an frame of the door when positioned parallel with respect to the ceiling of the car.

3. In a bulk-head construction ,the combination of a car, a doorway therein, a cross beam secured in the doorway near the upper part thereof and having slots therein, rails arranged in the upper part of the car, trolleys slidable on the rails, means. for limiting movement of the trolleys in one direction, depending arms pivotally secured with res ect to the trolley, bulk-heads secured to the epending arms, slide heads, props pivotally mounted to the bulkheads, rack bars having notches therein fixedly secured to the car, and other notched rack bars swingably secured ad"acent the doorway o f the ear, said notches o theseries of bars being adapted for engagement by the slide bolts of the gates whereby the bulkheads may be positionedlongitudinally withr respect to the car; the said bulk-heads being further adapted for pivotal movement with respect to the trolley whereby they may be swung to and retained in parallel position with respect to the upper part of the car.

In testimony whereof I have hereunto set my hand.
